Themicroprocessor 12 compares the identification code D01 to the comparison table T so as to find the corresponding action command Q1, and then controls the vehicleelectronic components 15 to execute the obtained action command Q1, for example, controls theAV multimedia system 151 to play a local landscape introduction film, a video film, or a musical, theheadlight system 150 to open or close, or theelectric windows 152 to open or close. - Further, the
input device 14 can be akeyboard 140, aCD reader 141, a wireless transceiver 16 (for example, mobile phone, PDA, pager, . . . ), card reader, etc. for inputting or editing the aforesaid comparison table T. By means of thewireless transceiver 16, themotor vehicle 1 can receive a variety of value-added services from aremote control center 4 through a wireless transmission. -
FIG. 3 is a schematic drawing showing one geographic zone according to the present invention. As illustrated, the aforesaid beacons B01, B02, . . . F15 are respectively located at different locations within the geographic zone. When themotor vehicle 1 is moving upwards (toward the north) from the lower left side shown inFIG. 3 through a beacon B01, the on-board short-distancewireless receiver 10 receives the wireless signal from the nearest beacon B01 to obtain the identification code B01 , and then compares the identification code B01 to the comparison table T to find and execute the corresponding action command. The action command can be defined to do no work (i.e. execute the action “Null”). For example, when passing through the circle on the lower left side shown inFIG. 3 , the on-board short-distance wireless receiver 10 of themotor vehicle 1 receives the wireless signal from the beacon D01 at the center of the circle, and themicroprocessor 12 searches the comparison table T to find the action command Q1 corresponding to the identification code D01 of the wireless signal from the beacon D01, and then executes the action command Q1 to drive theAV multimedia system 151 to play an introduction film that introduces the history of the sculptured statue at the center of the circle. - When the
motor vehicle 1 keeps moving northwards through a beacon B07 toward the tunnel, themicroprocessor 12 searches the comparison table T to find the action command Q2 and then executes the action command Q2. This action command Q2 is not to control the operation of the vehicleelectronic components 15 but to modify the enable flag in the comparison table T corresponding to the identification code B08. - This enable flag works like a switch. When at disable, the action command Q3 corresponding to the identification code of the beacon B08 will not be executed. When the
motor vehicle 1 passes through the beacon B07, the enable flag corresponding to the identification code of the beacon B08 will be changed to enable, and themicroprocessor 12 will execute the action command Q3 to close theelectric windows 152 and open theheadlight system 150 when themotor vehicle 1 passes through the beacon B08 after the identification code of the beacon B08 has been changed to enable. After themotor vehicle 1 passed through the beacon B08, the enable flag of the identification code of the beacon B08 is returned to disable. - In the same way, when keeps moving northwards, the
motor vehicle 1 will pass through a beacon B14 near the gateway before entering the highway, and will execute the corresponding action command Q7 searched from the comparison table T to change the enable flag of the identification code of the beacon A05 to enable. When passing through the beacon A05 at the entry of the highway, themicroprocessor 12 of themotor vehicle 1 will then execute the corresponding action command Q8 to provide the identification code of the beacon A05 and the license number of themotor vehicle 1 to thecontrol center 4, allowing thecontrol center 4 to know the location of themotor vehicle 1 and to trace the traveling of themotor vehicle 1. - When leaving the highway through an exit, the
microprocessor 12 of themotor vehicle 1 will execute the action command Q9 of the identification code of the beacon A13 and the action command Q10 of the identification code of the beacon E09, providing the identification code of the beacon E09 and the license number of themotor vehicle 1 to thecontrol center 4, so that thecontrol center 4 can control the traffic flow on the highway, adjust the traffic flow control at the entry, or even calculate the feed to be charged to every motor vehicle passing through the entry or exit (beacon A04 or A13) of the highway. - As stated above, the action commands Q1, Q2 stored in the
memory 11 corresponding to the identification codes of beacons B01, B02, . . . F15 can be triggered individually like a regular switch to control the operation of theelectronic components 15 of themotor vehicle 1, or to provide data to thecontrol center 4, enabling thecontrol center 4 to know the moving direction of themotor vehicle 1. - Further, the identification codes in the comparison table T can be arranged and classified by group and the classified groups of identification codes can be corresponded to different geographic groups N1, N2, . . . , to facilitate project planning. For example, A** indicates the area within A01˜A16 as shown in
FIG. 3 , i.e., all the beacons along the highway group N1. The so-called different geographic groups N1, N2, . . . means the plurality of beacons on the land are arranged in groups subject to the characteristics of their geographic environments, and the beacons within a same geographic environment are defined to be members of same group. For example, the beacons at a same street are defined to belong to same street group; the beacons at the streets around one parking lot are defined to belong to same parking lot group; the beacons in a tunnel are defined to belong to a same tunnel group; the beacons at a highway are defined to belong to a same highway group; the beacons in a business zone are defined to belong to a same business zone group; the beacons in an amusement park are defined to belong to a same amusement park group; and so on. - Therefore, the aforesaid grouping prototype facilitates establishment of the comparison table T and its effective application. Establishing the comparison table T by the aforesaid grouping prototype greatly reduces the amount of data and the size of the electronic file of the comparison table T, allowing fast renewal of the comparison table T during a repair work of the
motor vehicle 1 at the motor vehicle shop or factory or update of the comparison table T by thecontrol center 4 through thewireless transceiver 16 or by theCD reader 141. - Referring to
FIG. 3 again, some of the identification codes of the beacons B01, B02, . . . F15 work subject to other control conditions, and the control conditions subject to the comparison table T include Time/Data parameter, Speed parameter, and Enable flag parameter. The control conditions may include other matters such as Altitude/Latitude parameter, Elevation parameter, Temperature parameter, . . . etc., or other Boolean expression combinations. According to the present preferred embodiment, themicroprocessor 12 controls execution of the corresponding action command only after the control conditions have been checked to meet the requirements. For example, when themotor vehicle 1 passes through each beacon A** during its movement on a highway, the speed of themotor vehicle 1 will be detected, and the identification code of the beacon A** with Boolean logic and of Speed parameter will not be established if the speed of themotor vehicle 1 is below 90 km/hr when moving on a highway through the beacon A07, and therefore the action command Q6 will not be executed. However, if the speed of themotor vehicle 1 is over 90 km/hr when passing through the beacon A08, themicroprocessor 12 will execute the action command Q6 to drive themultimedia system 151 to output a warning voice of speeding. - Other control conditions such as to execute the action command Q4 under the condition that the identification code grouping*** to be any identification code and the Time/Date parameter to be 17:00PM˜08:00AM. In this case, the
microprocessor 12 will detect the current time when passing through any beacon B01 and will open theheadlight system 150 if the current time is detected to be 17:01PM. Further, there is another condition with date included, for example, when themotor vehicle 1 passing through the beacon E07 nearSogo Department Store 60, themicroprocessor 12 will detect the current time and date and will execute the action command Q5 to drive themultimedia system 151 to play Sogo Department Store Promotional Film if the date is detected to be within November 1st˜15th and the time is detected to be within 10:00AM˜22:00PM. - Further, in the aforesaid comparison table T, the control conditions (for example, Time/Date parameter, Speed parameter, Enable flag parameter, . . . etc.) corresponding to the identification codes of the beacons B01, B02, . . . F15, the corresponding action commands, and their related relationship are editable and renewable so that a specific effective comparison table T can be established to fit the requirements of every
individual motor vehicle 1. - The effectiveness of the present invention will become more prominent in a sheltered area. As shown in
FIG. 3 , when themotor vehicle 1 entered theunderground parking lot 61 in the City Hall, GPS satellite signal is blocked, and remote wireless communication systems such as GSM mobile telephones will produce a significant determination error on triangle positioning or signal strength positioning method due to Multipath Interference, Inter Symbol Interference, or Decay. At this time, the all over beacons of the present invention allow accurate positioning or can still provide services.FIG. 4 is a plain view of the underground parking lot of the City Hall. As illustrated, when themotor vehicle 1 passing through the beacon F01 at the entrance, themicroprocessor 12 of themotor vehicle 1 executes the corresponding action command Q11 to report to thecontrol center 4. When leaving the parking lot and passing through the beacon F01, themicroprocessor 12 of themotor vehicle 1 will report to thecontrol center 4 again. Subject to the two reported data from themotor vehicle 1, thecontrol center 4 can calculate the parking time of themotor vehicle 1 and the related parking fee. During parking of themotor vehicle 1, themotor vehicle 1 can also be controlled to drive multimedia system to play voices, advising the driver to turn off motor vehicle lights and locking motor vehicle doors (action command Q12). Furthermore, it can be known the remained parking space bye the beacons F02˜F15. - Referring to
FIG. 1 again, the aforesaid B01, B02, . . . F15 can be connected in series to thecontrol center 4 by asignal line 41 several kilometers long. Alternatively, thecontrol center 4 can use a short-distance wireless transmitter 42 and the short-distance wireless receiver 43 to achieve two-way communication with the short-distance wireless transmitters 22, 32 andwireless receivers control center 4 can send data to the beacons B01, B02, . . . F15 by wire or wirelessly, enabling the data to be further sent to themotor vehicle 1 by the beacons B01, B02, . . . F15 to provide a variety of services, such as updating of the comparison table T, friend match, inquiry of sales centers, shopping in vehicle, inquiry of traffic conditions, . . . and etc. - Further, the
control center 4 can provide the beacons B01, B02, . . . F15 with a new identification code.FIG. 5 is a schematic drawing of the geographic zone after modification of identification codes.FIG. 6 is a schematic drawing of the updated comparison table. If an ambulance (not shown) is going to pass through the road at the right side inFIG. 6 that extends from the south toward the north, thecontrol center 4 can send a new comparison table T (with added identification code ZZZ and the related action command Q13) to thewireless receiver 16 of themotor vehicle 1 wirelessly, enabling the new comparison table T to be stored in thememory 11 by themicroprocessor 12. Thereafter, thecontrol center 4 changes the identification codes of the beacons E01˜E09 at this specific road to become ZZZ. Thus, anymotor vehicle 1 entering this road will execute the action command Q13 to drive themultimedia system 151 to play voices of pulling over themotor vehicle 1, advising the driver to move over to the side of the road for allowing the ambulance to pass. - Further, because the beacon B01 is equipped with a short-
distance wireless receiver 23 and themotor vehicle 1 has an on-board short-distance wireless transmitter 13, the beacon B01 can provide simple services to themotor vehicle 1 without the help of thecontrol center 4. As illustrated in the friend matching system ofFIG. 7 , the driver of themotor vehicle 1 and the driver of the motor vehicle 7 have initiated the fried match service. At this time, the short-distance wireless receiver 23 of the beacon B01 receives the personal signal S from themotor vehicle 1, which personal signal S contains personal data including name, telephone number, sex, age, and etc, and then sends the received personal signal S to the other motor vehicle 7 through the short-distance wireless transmitter 22, enabling the driver of the motor vehicle 7 to make communication with the driver of themotor vehicle 1. Thus, the friend matching service is done. - Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed.
